Application April 18, 1952, Serial No. 283,023

1 Claim. (Cl. 155-17) This invention relates to a spring base for baby jumper chair, and more particularly toa spring supporting base adapted to have detachably mounted thereon a chair which can be moved up and down in a springing manner as it is held on said spring base.

Among the salient objects of the invention are:

To provide a simple, practical and economical spring base, complete in itself, and upon which a childs chair can be mounted and removed at will, and without the use of special tools;

To provide in connection with such a spring base and as a part thereof, a base plate for the feet of the child occupying the chair, and to which base plate said spring base side members are hingedly connected, said side spring members being hinged in such a way that they cannot fall or move outwardly;

To provide a spring base unit which can be folded flatwise upon said base plate in small compass for shipping purposes;

To provide a spring base unit of the character referred to having on its spring side members means for receiving and holding a chair in upright position for use, with latch means therefor, whereby said chair can be easily and quickly removed from said spring base at will;

While I have shown a childs chair in connection with said spring base, it will be understood that said base can be made to receive and hold an adult chair for the up and down springing action. I have also shown a chair having side members, the upper ends of which are formed into hooks to hook over the back of an automobile seat for carrying a child in an automobile, in a well known manner, said hooks being foldable flatwise against the back of the chair.

In order to explain my invention more in detail, I have shown on the accompanying sheet of drawings one practical embodiment thereof, which I will now describe.

Figure 1 is a perspective view of one embodiment of the invention, with a chair held therein for use;

Figure 2 is an enlarged fragmentary view of one of the holding means, with one of the side back members of a chair in place therein, and showing a latch element for locking the chair in place; and

Figure 3 is a sectional view taken on the line 3-3, Fig. 2.

Referring in detail to the drawings, the invention as here shown for explanatory purposes, includes two spring side members, 4, 4, here shown in the form of spring loops, preferably made of flat spring metal. A base plate, designated 5, is shown with its forward edge bent into an angle, as at 5', to give stiffness thereto. Said spring side members are hingedly connected at their inner edges to the outer edges of said base plate, as at 6, whereby said side spring members can be folded toward each other flatwise upon said base plate. It will also be noticed that the outer edges of said spring side members rest flatwise upon the outer edges of said base plate in such a manner that they cannot fall or move outwardly, but will stand up- ICC right, and flatwise upon the outermost edges of said base plate.

In the present form of the spring side members, each is formed of one piece of spring metal, bent as shown, to form an intermediate C-spring portion, as 7, riveted or otherwise secured at its ends to the top and bottom middle portion of the main side spring member, as at 7" and 7', whereby to give additional strength to the side members 4, 4, at the place where the chair-supporting means are secured.

Upon each of said side spring members 4, 4, at the juncture of the upper portion of the C-spring 7, is an angle plate 8, depending therefrom, as at 8. On the inner side of each depending plate 8 is secured an S-shaped member 9, seen in section in Fig. 3, in one channel of which the tubular side member of a chair is inserted, as shown at S, in Figs. 2 and 3. Mounted through the other channel of said S-shaped member 9, transversely thereof, is a U-shaped latch member 10, the ends of which are yieldingly inserted into holes, as 10', in the side member S of the chair, as clearly indicated. Two coiled springs, 11, 11, on the legs of said U-shaped latch, in said other channel of the S-shaped member 9, operates to normally move the legs of said latch member into said holes 10' in said side members, it being understood that. there is a latchlock at each side of the chair and on each of said side spring members 4, 4. It is only necessary to manually pull said latch members outwardly to release the chair and permit it to be removed from the supporting spring base.

The upper ends of the tubular side members of the chair are formed into hooks, as 11', to be hooked over the back of an automobile seat when it is desired to have the baby chair so supported. These hook portions 11 are foldable flatwise together upon the back of the chair. The forwardly extending loop 12, which supports the seat of the chair, is also foldable fiatwise up against the front of the back of the chair, in a manner which makes said chair flat and easily packed with the folded spring side members, before referred to, in a comparatively small box for shipment.

The little tray 13, on the front of the chair, has a top supporting loop, as 14, the opposite ends of which are designed to be inserted into holes in the seat-supporting frame, as at 15.

Thus I have provided a simple, practical and economical spring base for supporting a chair so it can be moved up and down in a springing manner, and which can be easily disassembled and folded into small compass for shipping.

I am aware that changes in the details of construction and arrangement can be made from what is here shown without departing from the spirit of the invention, and I do not, therefore, limit the invention to these details, shown only for explanatory purposes, except as I may be limited by the hereto appended claim.

I claim:

A spring supporting base for a chair, including a base plate, two spring loop-like members of flat spring metal having their lower sides straight and set upon the opposite edges of said base plate and hingedly secured thereto along their inner edges, whereby to be foldable together flatwise upon said base plate, each of said members having a C-shaped spring portion between its top and bottom to give additional springing strength, each of said looplike members having on its inner top side an angle plate secured to the top of said loop-like member and to the top end of said C-shaped spring portion and depending on the inner side thereof, an angle member secured to the inner side of said depending plate and having an inwardly opening channel to receive the side member of a chair, and an outwardly opening channel to receive a spring ac- 3 mated latch member therethrough for locking the side member of a chair in place in said channel.
